7 Purpose of this Catalog INTRODUCTION DO NOT USE THIS CATALOG AS AN ASSEMBLY OR INSTALLATION DOCUMENT. THIS CATALOG MUST ONLY BE USED TO IDENTIFY PARTS IN CONJUNCTION WITH THE APPLICABLE OVERHAUL MANUAL. This Illustrated Parts Catalog (IPC) contains a complete list of spare parts for the Lycoming (L)IO- -M1A wide cylinder flange model engine. How to Use this Catalog This catalog is based on the Air Transport Association (ATA) Spec 100 format. In order to clarify illustrations, Lycoming has taken discretion to classify non-system related assemblies and components in the same chapters, because they are physically connected. This catalog is frequently updated by Service Bulletins (SB) and Service Instructions (SI). The updated information will be incorporated into subsequent full revisions of this catalog. The ATA two element numbering system provides consistency throughout various manuals. The bottom of each page (beyond the frontal section) contains a two element number (##-##). In the two element numbering, the first two digits represent a chapter, and the next two digits subdivide the material into a more specific section. The ATA format specifies the subject matter for each chapter-section. According to the ATA Standards, the following chapters apply to the (L)IO--M1A Illustrated Parts Catalog: 24 (Electrical Power), 72 (Reciprocating Engine), 73 (Engine and Fuel Control), 74 (Ignition), and 80 (Starting). NOTE: Numerical Index EXAMPLE: Chapter Ignition Section Distribution See the IPC Table of Contents for the sub-systems listed in each section. The Numerical Index is a single list of part numbers, names and their locations within the IPC. It is useful for locating parts when you only know the number or name of the part. Description column Indentation of a part name represents a lower level of assembly. Attaching parts have the same indentation level and are listed below the parts grouping or assembly they attach to. This column is often referred to as the "Nomenclature" on other ATA Spec manuals. Units per Assembly Column Where more than one assembly exists, this column contains the quantity of a specific part required in the build sequence of only one next higher assembly. The letters AR represent as required for bulk items or non-illustrated select-from-range-parts. RF represents items listed for reference purposes only.

8 Cross-Reference List of Manufacturer Parts to Standard Part Number Vendor Accessories Parts coverage of Vendor Accessories used on Lycoming engines may be found in the appropriate Vendor s Parts Catalog. A list of vendor s addresses appears in the latest revision of Lycoming Service Letter No. L114. Any reference in this document to the suppliers/part manufacturer s product, by name, trademark, part number or other description is solely for the purpose of identification and does not indicate or infer that Lycoming accepts responsibility for quality control and/or airworthiness of parts, which do not pass through the Lycoming quality control system. Environmental Compliance Lycoming is concerned with preserving the environment. Lycoming strongly urges engine owners and repair/overhaul personnel to observe and comply with all federal, state, and local environmental regulations when solvents, paint, fuel, oil, chemicals, or other consumables are used in operating, maintaining, or overhauling an engine component. Please share our concern for, and commitment to a clean earth, clean water, and especially clean air for succeeding generations of flyers.

9 Perspective of References In this manual, all references to locations of various components will be designated as if viewing the engine from the rear (or anti-propeller) end. The front of the engine is considered to be the propeller end and the oil sump is considered to be on the bottom of the engine. Cylinders are numbered from front to rear with the odd-numbered cylinders on the right-hand side.
